appropriate, use cruise control, if equipped.
.Always follow posted speed limits or drive more
slowly when conditions require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same TPC
Spec number molded into the tire's sidewall near
the size.
.Follow recommended scheduled maintenance.

If the passenger seat gets wet, dry the seat
immediately. If the airbag readiness light is lit, do
not install a child restraint or allow anyone to occupy
the seat. SeeAirbag Readiness Light
on page 4‑27for
important safety information.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat. If this
is not desired, remove the object from the seat.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the service
manual have information about servicing the vehicle
and the airbag system. To purchase a service manual,
see Service Publications Ordering Information
on
page 8‑14.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run
if you follow these guidelines:
.Do not drive at any one constant speed,
fast or slow, for the first 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake or slow the vehicle.
.Avoid making hard stops for the first
200 miles (322 km) or so. During this time
the new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
.Do not tow a trailer during break-in. See
Towing a Trailer (Automatic Transmission)
on page 5‑32or Towing a Trailer (Manual
Transmission)
on page 5‑40for the trailer
towing capabilities of your vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.

Automatic Transmission Operation
If the vehicle has an automatic transmission, the shift
lever is located on the console between the seats.
There are several
different positions for the
automatic transmission.
P (Park): This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park (Automatic Transmission)
on page 3‑36.
If you are pulling a trailer, see Towing a Trailer
(Automatic Transmission)
on page 5‑32or
Towing a Trailer (Manual Transmission)
on
page 5‑40
.
3-28

D (Drive):This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
.Going less than about 35 mph (55 km/h), push
the accelerator pedal about halfway down.
.Going about 35 mph (55 km/h), push the
accelerator all the way down.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
under Loss of Control on page 5‑15.
I (Intermediate): This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving on
hilly, winding roads and when towing a trailer, so that
there is less shifting between gears. PERFORMANCE SHIFTING:
If the vehicle has this
feature, it can detect a change in driving patterns
while in the Intermediate position. If you make an
aggressive driving maneuver, the vehicle's transmission
automatically shifts to the lowest possible gear to
maximize vehicle performance. The vehicle will
automatically return to normal operation when you
return to normal driving patterns.
L (Low): This position reduces vehicle speed more than
I (Intermediate) without actually using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in L (Low), the transmission will
not shift into L (Low) until the vehicle is going slowly
enough.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.

Shifting Into Park
(Automatic Transmission)
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer
(Automatic Transmission)
on page 5‑32or
Towing a Trailer (Manual Transmission)
on
page 5‑40
.
To shift into P (Park): 1. Hold the brake pedal down and set the parking brake. See Parking Brake
on page 3‑34for more
information.
2. Move the shift lever into P (Park) by holding in the button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
Leaving the Vehicle With the Engine
Running (Automatic Transmission)
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave an automatic transmission vehicle
with the engine running, be sure the vehicle is in
P (Park) and the parking brake is firmly set before
you leave it. After you have moved the shift lever into
P (Park), hold the brake pedal down. Then, see if you
can move the shift lever away from P (Park) without first
pushing the button. If you can, it means that the shift
lever was not fully locked into P (Park).
3-36

If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting
on page 6‑41for more information.
To shift out of P (Park): 1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park): 1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking the Vehicle
(Manual Transmission)
Before leaving the vehicle, fully press the clutch pedal
down, move the shift lever into R (Reverse), and firmly
apply the parking brake. Once the shift lever has been
placed in R (Reverse) with the clutch pedal pressed
down, the ignition key can be turned to LOCK/OFF, then
remove the key and release the clutch pedal. See
Manual Transmission Operation on page 3‑31.
Parking Over Things That Burn
{WARNING:
Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
